Enum ContractCallError 

pub enum ContractCallError {
    NoReturn,
    TypeMismatch(String),
    Panicked(String),
    Wasm32CrossCallUnavailable {
        syscall: &'static str,
    },
    Other(NeoError),
}

Error type for the L9 typed-call helpers. Reserved for future use (the L6 cross-call executor will return this rather than panicking with “see L6 design”).

Variants

NoReturn

The call returned no value.

TypeMismatch(String)

The call returned a value of the wrong type.

Panicked(String)

The call panicked (L6: cross-call executor will replace this with a proper Result).

Wasm32CrossCallUnavailable

L6 minimal: the wasm32 cross-call stub (System.Contract.Call / System.Runtime.LoadScript / System.Contract.CallNative) was invoked, but a real wasm32 cross-call executor is not yet implemented. The contract author can match on this variant and degrade gracefully (e.g. return a default value) instead of crashing the VM.

Fields

syscall: &'static str

Other(NeoError)

Other (delegated from NeoError).

Trait Implementations

impl Clone for ContractCallError

fn clone(&self) -> ContractCallError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ContractCallError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ContractCallError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for ContractCallError

impl Error for ContractCallError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<NeoError> for ContractCallError

fn from(e: NeoError) -> Self

Converts to this type from the input type.

impl PartialEq for ContractCallError

fn eq(&self, other: &ContractCallError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
